After its last refit, the old battleship USS Mississippi was absolutely loaded with secondary/tertiary weapons. 5"/25s stuck everywhere, 40mm quads all over the place, and a few 20mm twins just for fun. Just completed a model of her in April 1945. It was, to say the least, a ton of work. Still have to find and paint a Kingfisher for the catapult at the stern. here are some photos of her. More photos are in the USA WW2 Battleships gallery on my website, which is "miniaturemodeling.com". Enjoy.
